Growing Campanulas indoors is not that difficult, provide bright light a east or south facing window and artificial light (During winter) and keep soil evenly moist but not overwatered. After most of the blooms are spent prune the plant down to about an inch above the soil and let it re-grow and it should re-bloom again. Feed them a very diluted blooming plant food at about half the strength until late spring then go to normal feedings as directed on the label. Artificial light should be kept on for at least 13 hours per day and plant should be about 6″ underneath grow light.
